Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge

Note :- In my Catia software Drafing Is Not opening So, The Mentor Saids Me To Send The Jpeg File You make in Student Version

Aim - To Flatten the harness assembly completed in “ week 4 challenge”. Place the flattened view on drawing sheet. Ensure bundles with protective coverings has different visuals on drawing view.

  CONNECTOR DEFINATIONS IN CATIA V5

  1. Deutsch DT06 – 08SA

  Connector connection point: Create midpoint on the contact face which will be normal to wire bunddle insertion

• DT06-4S

• DT06-6S

• DT06-2S

Steps Involved:

1.Preparation of Harness Assembly:

Create a master product file(Harness Context Assembly) and two sub-level product files named Geometrical Bundle & Electrical Bundle respectively.(Ref Below image).

• Insert all the required Surrounding Part data into the Master Product file.
• Save the master product file in a desired location.

2.Creating the Wire harness Geometrical Bundle:

• Once Geometrical Bundle is created, then open it in a new window.
• Select the "Geometrical Bundle" command and then click on Product Icon in Model tree to convert it into an Electrical Assembly.(Ref Image below)

3.Inserting Harness Components into Geometrical Bundle:

• Before Inserting the components, ensure that all the required components have been electrically defined.
• Once the required components were defined electically, then insert them using Catalog Browser command or using existing component command(ref below image)

4.Positioning the Inserted Components:

• Before start routing, ensure all the components in it's desired location according to surrounding data.
• If not then place and position the components by using any of the following commands like Manipulation, Translation or Rotation,Snap,Smart Move,Compass.(ref below image)

5.Connect and Disconnect Electrical Devices: If there are any assembly that need to be assembled before routing like Connector with Mounting Clip or Connector with backshell. Then Assemble them using "Connect Electrical" Devices

6.Defining the Wiring Harness Routing:

• Creating Wire Harness with Single Branch:

1. Switch to Electrical harness Assembly Workbench.
2. Select Multibranchable Document Icon.
3. In the Branch Definition Box(Ref Below Image) ,describe all the required paramters like Diameter,Bend Radius(>1.4),Build mode(slack,Length,Bend,Straight Bend).
4. Click Route Definition and select the two components that you need to route.
5. Click OK

Creating Wire Harness with Multible Branches:

1. Switch to Electrical harness Assembly Workbench.
2. Select Multibranchable Document Icon.
3. In the Branch Definition Box ,describe all the required paramters like Diameter,Bend Radius(>1.4),Build mode(slack,Length,Bend,Straight Bend).
4. Click Route Definition and select the two components that you need to route.
5. Click OK.
6. Once the Multibranchable is created, Click Add branch point command and define the point on the main branch where the Harness Branch needs to be created.
7. Repeat the steps from "c to e"
8. Add protective covering on the required branches by using Protective Covering Command and mention the start and end extremity points.

Conclusion: Thus, the Wiring Harness Layout has been designed with the given inputs and the protective coverings also added on the required branches(ref below image)

To make a flattened view of any wiring harness we should be working in the Electrical Harness Flattening workbench of CATIA V5. We should make sure that the flattening file should be in the same folder where you have all the parts of the harness assembly.

CONTENT-

The following steps are to be done to complete this project.

STEP1- Defining Harness Flattening parameters

First, we should make a new product file inside the Electrical Harness Flattening workbench. Second, we should define the harness flattening parameters by clicking on its icon as shown above. In the general tab, we should select the settings as shown above. After the general tab settings are complete we should define the settings for the drawing tab as shown below.

It should be noticed that the type of representation for the bundle segment and protective covering are different from each other. Also for devices, "3D projection" can be used if the connectors are added to the electrical drawing catalog.

STEP 2- Rename the product file as the Flattening Product.

STEP 3- Bring the harness assembly into the newly created Flattening Product by using the "Extract" feature.

Next Create a Drawing
